With the news that over half of the trillions of Google searches happen on mobile, Google announced Tuesday that it will soon change the way advertisers set bids for targeting ads by device type in AdWords. Other coming changes announced at Googler Performance Summit in San Francisco include an update to Google text ads on all devices and responsive mobile display ads that can access native mobile ad inventory on the Google Display Network. The change in bidding is significant in that it accomplishes two things: 1. Untethers desktop and tablet bids; and 2. Allows advertisers to make mobile the focal point of their campaigns. Advertisers will be able to set separate bid adjustments for mobile, desktop and tablet. “This lets you anchor your base keyword bid to the device most valuable to your business and then set bid adjustments for each of the other devices. You will also have a wider range to adjust bids, up to +900%,” explained Sridhar Ramaswamy, Senior Vice President, Ads and Commerce, in the blog post announcing the update. The news was also announced during Google Performance Summit in San Francisco. Get the full story at Marketing Land and Search Engine Watch
